问题 What is the difference between the apk file in the bin folder and the apk file created through the Export option in Eclipse? For debugging purposes, can I directly use the file in the bin folder?

问题 When I install my app on my main/new phone, the installed size is around 18.5MB and when I install my app on an old Samsung Galaxy Ace (Mk1), for some reason, it installs with pretty much the same size, as you see here: It runs perfectly on my main phone, but obviously, the old Galaxy Ace really struggles with it.
